3To whom also he showed himself alive after his passion by many infallible proofs, being seen of them forty days, and speaking of the things pertaining to the kingdom of God:

5For John truly baptized with water; but ye shall be baptized with the Holy Ghost not many days hence.
That's the promise that Jesus was referring to.
Well, If Jesus has everything Please explain this passage to me.
1 The LORD said unto my Lord, Sit thou at my right hand, until I make thine enemies thy footstool.
2 The LORD shall send the rod of thy strength out of Zion: rule thou in the midst of thine enemies.
3 Thy people shall be willing in the day of thy power, in the beauties of holiness from the womb of the morning: thou hast the dew of thy youth.
4 The LORD hath sworn, and will not repent, Thou art a priest for ever after the order of Melchizedek.
5 The Lord at thy right hand shall strike through kings in the day of his wrath.
6 He shall judge among the heathen, he shall fill the places with the dead bodies; he shall wound the heads over many countries.
7 He shall drink of the brook in the way: therefore shall he lift up the head.
And again, please explain to me what this has to do with John 6.
